摘要
采用含有过氧化物的聚丙烯(PP)母粒,通过熔融共混法制备了不同熔体流动速率(MFR)的PP/炭黑导电复合材料,并研究了复合材料的流变性能、结晶性能、力学性能及导电性能。结果表明:PP过氧化物母粒的加入有效改善了PP/炭黑导电复合材料的流动性。PP过氧化物母粒质量分数为2.2%时,复合材料的结晶度是25.96%,拉伸强度、冲击强度分别达到25.96 MPa、73.70 kJ/m^2。PP过氧化物母粒的加入对复合材料导电性能的影响较小。
Polypropylene(PP)/carbon black conductive composites with different melt flow rates(MFR)were prepared by melt blending with PP masterbatch containing peroxide.The rheological properties,crystallization properties,mechanical properties and electrical conductivity of the composites were investigated.The results show that the addition of PP peroxide masterbatch effectively improves the fluidity of PP/carbon black conductive composites.When the amount of PP peroxide masterbatch is 2.2%,the crystallinity of the composite is 25.96%,and its tensile strength and impact strength reach 25.96 MPa and 73.70 kJ/m^2,respectively.At the same time,the addition of PP peroxide masterbatch has little effect on the electrical conductivity of the composites.
